Open the full vehicle complaint log (all categories)This is now the second time this has happened on my brand new 2023 Jetta SE. The vehicle only has 1831 miles on it. The fault happens when the car is being driven after approx. 15 minutes. EPC light, Check Engine Light, and Yellow Warning Light illuminate. Also sounds like a misfire when limping off the road. Codes read at dealer are P0304, P0363, P1D74, and P1D75. All of these codes relate to Cylinder 4 misfire. Car is driven only at highway speeds, since it is a commuter car. This happened on 2/16/2024 and 2/22/2024. I attached PDFs of the Service Invoice from the first instance. I also attached a PDF of a NHTSA file containing a list of VW vehicles that are having the same issue, with the same engine.
The follow failed module faults have REPEATEDLY FAILED: U010400 lost communication with cruise control module, U112100 databus missing message & U112300 databus error value received, C110BF0 Adaptive Cruise Control Sensor, C111207 Haldex Clutch Pump Mechanical Malfunction, P030400 Cyl 4 Misfire, ***P085000 Park/Neutral Switch Input Circuit Open or Short***, U105400 Information Electronics Control Module 1 No Communication. I’ve had it repaired once by VW. Been at dealership multiple times for all of these issues. Currently, they are not helpful. My car does not recognize PARK, it thinks it’s in NEUTRAL.
